Google said that by replacing DNS resolvers with DoH alternatives from the same providers, this way, any DNS-based filters and parental controls set in place at the DNS provider's level will remain intact. As DoH support will expand later down the road to also include DNS servers provided by internet service providers (ISPs), this "same provider switching" mechanism will prevent DoH from bypassing DNS-based filters set up at the ISP levels, sometimes put up to prevent access to child abuse content or legally mandated by country-level blocklists.
